Serial Data Configuration

In order for the host device that is connected to the master port to select any of the five ports, the Smart Switch must be set to match the host's communication format. Dipswitch “SW1” is used to select the communication format of the Smart Switch. Switch positions 1 through 3 select the baud rate. Switch position 4 selects 7 or 8 data bits. Switch position 5 determines if parity is enabled or disabled.

NOTE: A data format of 7 data bits, no parity and one stop is not allowed.

Switch position 8 selects the port configuration, see section titled "Port Configuration". Refer to Table 1. Always power down the smart switch when changing switch settings.

RS-485 Support

RS-485 support may be provided by adding a Model 485SD9TB RS-232 to RS-485 converter or other recommended device to the slave ports of the 232XS5.

Port power of about 30 mA may be applied through the DTR line (Pin 4) of the slave ports with jumper JP1-JP5. Normally, the jumpers are set to allow DTR to pass from the master port. To enable port power on a slave port, move the jumper from the“OFF” to “ON” position on the corresponding JP jumper. To allow DTR to pass from the master port to the slave port, move jumper from “ON” to “OFF” on the corresponding JP jumper. DTR can only pass through when the port is selected and the jumper is set to the “OFF” position on the corresponding slave port JP jumper.
